It will be noted that bythis arrangement, all. the mechanism is contained in the driving anddriven shafts which makes the apparatus simple of manufacture andeflicient in operation. It also will be noticed that each of the ballsxv'l' heid in its retra ed or innermos. by the spring' j a tha t' thereor jar by the ear. 11, which are not transiniUM t ie power.

It is miderstood, of course, that the shafts and parts are mounted inthe usual bearings farmed in the' gear boX, which it is no1 thought'necessary to showI and describe in this application as they may be ofany ordinary or approvedv construction.

Many modifications of thearrangements herein shown and described maymade by a. skilled mechanic Without departing from rigs Titi.

'the scope of my invention as expressed in the claims.

Havin thus fnllydescribed my invention. what I c aim and desire tosecure by Letters Patent, is

1. In a transmission caring, the combinationof a shaft, a series ofgears loosely arranged thereon and having recesses formed on the insidethereof, balls arranged in holes cut in the shaft, means for forcing anyball outwardly to engage and lock any gear to the driven shaft, andmeansfor normally holdingr the balls 'in their innermost or re tractedposit'on.

2. l'n a tr mission gearing, the conibi. :nation oil' a shaft, aseries'of gears loosely s4 'anni-"d the ion and having recesses formedonine iside thereof, balls arranged in holes cnt in the shaft, means forforcing any ball out-nf'zlrdly to engage and loch'. any gear to thedrivenshaft, and springpressed pilingers for normally holding the ballsin their retracted posit-ibn.

In testimony whereof I have hereunto set my hand, in the presence of twosubscribing Witnesses.
